Eisenmann "Sport" Loss of HP?

Is it true that with the Eisenmann Sport you may lose power hp since they use more chambers to quite the sound? Someone told me if I were to get either sport/race to go with race so I would not lose any hp and maybe gain a few. I dont want the obnoxious sound of the race but dont want to lose hp either... Thanks in advance.

maybe you might want to try another brand such as supersprint, rdsport?

Last time I heard, the supersprint race is way more civilized than eisenmann race

I think even e-sport still better than stock in term of air-flow. Nobody ever proof it lose power, but again it will not gain you power as well. Exhaust on S85 just for sound, IMO.

I actually think the cars feels faster with the e-sport. I'm only going off the butt dyno but I actually notice more difference with the exhaust than I do with the removal of the charcoal filters.

Just the opposite for me. First thing I noticed with the E-sport was loss of low end torque. Our butt dynos are definitely calibrated differently....

The sport is less free flowing then the race, but I am not sure if it exactly losses power compared to stock. That being said, race is the better bet in terms of flow and sound (although it is very loud). I find the SuperSprint to be too tame for my tastes...

Boston Rocket told me his Race is too loud.... Im confused.... maybe the Meistercheif would be an option since it is in between sport and race....

I have SS headers with the SS Sport muffler and it is perfect for me. It is certainly louder than stock but not by much. Now if you go with the sport cats I am sure it would take it to another (sound) level.
